Navigation/Radio System
Your vehicle may have a navigation radio system that
includes Radio Data System (RDS) with Program
Type (PTY) selections that will seek out the kind of
music you want to listen to and XM™ Satellite Radio
Service capabilities (if equipped). The radio can
also communicate with the navigation system to
broadcast announcements on traffic, weather, and
emergency alert communications. For information on
how to use this system, see the “Navigation System”
manual.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. The feature works automatically by
learning a portion of the Vehicle Identication Number
(VIN). If the radio is moved to a different vehicle, it
will not operate and LOCKED will appear on the display.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
®is armed.
With THEFTLOCK
®activated, the radio will not operate
if stolen.
Radio Reception
You may experience frequency interference and static
during normal radio reception if items such as cellphone
chargers, vehicle convenience accessories, and
external electronic devices are plugged into the
accessory power outlet. If there is interference or static,
unplug the item from the accessory power outlet.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause
station frequencies to interfere with each other. For
better radio reception, most AM radio stations will boost
the power levels during the day, and then reduce
these levels during the night. Static can also occur when
things like storms and power lines interfere with radio
reception. When this happens, try reducing the treble on
your radio.
FM Stereo
FM stereo will give the best sound, but FM signals will
reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to fade in and out.

Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-33.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
4-7

The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.
As you brake, your computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may feel
the brakes vibrate, or you may notice some noise,
but this is normal.
Braking in Emergencies
With anti-lock brakes, you can steer and brake at the
same time. In many emergencies, steering can help you
more than even the very best braking.
4-8

Traction Control System (TCS)
Your vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that any of the wheels are spinning or beginning to lose
traction. When this happens, the system applies the
brakes to limit wheel spin and also reduces engine
power. You may feel or hear the system working, but
this is normal.
The Traction Control System may operate on dry roads
under some conditions. When this happens, you may
notice a reduction in acceleration or a pumping sound.
This is normal and doesn’t mean there’s a problem with
your vehicle. Examples of these conditions include hard
acceleration in a turn, an abrupt upshift or downshift of
the transmission or driving on rough roads.
If your vehicle is in cruise control when the TCS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re-engage the cruise control. See
Cruise Control on page 3-11.
If your vehicle has a Driver information Center (DIC), a
TRACTION FAILED message will appear when a
Traction Control System or Anti-Lock Brake System
problem has been detected and the vehicle needs
service. SeeDIC Warnings and Messages on page 3-44
for more information.When this message is on, the system will not limit
wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to.
To turn the system off,
press and release the TCS
button located on the
instrument panel.
This light will come on
steady when the traction
control system has
been turned off. This
light ashes when TCS
is active.
4-9

If you press the TC button once, the traction control
system will turn off and a TRAC OFF message
will appear on the DIC. Press the TC button again to
turn the system back on. The TRAC OFF message will
then go off. The traction control system will reset
itself at each ignition cycle. If your vehicle also has
StabiliTrak
®, seeStabiliTrak®System (Automatic
Transmission) on page 4-11for more information.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3for more information.
Locking Rear Axle
Your vehicle may have this feature. The locking rear
axle can give your vehicle additional traction from the rear
wheels when traveling in off-road situations such as mud,
snow, sand, steep hills and uneven terrain.
The button used to turn
this feature on or off is
located to the right of the
transfer case buttons
on the center of the
instrument panel.To lock the rear axle, do the following:
1. Place the transfer case in the 4LO Lock mode. This
is the only mode which will allow the rear axle to
lock. SeeAll-Wheel Drive on page 2-22for
more information regarding the transfer case and
4LO Lock mode.
2. Press the button with the vehicle stopped or moving
less than 2 mph (3 km/h).
You must wait for the light in the button to stop ashing
and remain illuminated before the rear axle is locked.
Notice:If you try to lock the rear axle while
your vehicle is stuck and the tires are spinning, you
could damage your vehicle’s drivetrain. The
repairs would not be covered by your warranty.
Always lock the rear axle before attempting
situations and/or navigating terrain which could
possibly cause the vehicle to become stuck.
The locking rear axle will be disengaged when the
wheel speed is greater than 20 mph (32 km/h), if the
vehicle’s battery is low and/or the transfer case is shifted
out of 4LO Lock mode.
Notice:If you lock the rear axle while driving on
pavement, you could damage your vehicle’s
drivetrain. The repairs would not be covered by
your warranty. Do not use the locking rear axle on
pavement. If you need four-wheel drive when
traveling on pavement, use only 4HI.

StabiliTrak®System (Automatic
Transmission)
Your vehicle may be equipped with a vehicle stability
enhancement system called StabiliTrak®.Itisan
advanced computer controlled system that assists you
with directional control of the vehicle in difficult
driving conditions.
StabiliTrak
®activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling. StabiliTrak
®
selectively applies braking pressure at any one of
the vehicle’s brakes to assist the driver with keeping the
vehicle on the intended path.
When you rst start your vehicle and begin to drive
away, the system performs several diagnostic checks to
insure there are no problems. You may hear or feel
the system working. This is normal and does not mean
there is a problem with your vehicle.
If there is a problem detected with StabiliTrak
®,a
SERVICE STAB SYS message will be displayed on the
Driver Information Center (DIC). SeeDIC Warningsand Messages on page 3-44for more information.
When this message is displayed, the system is
not operational. Adjust your driving accordingly.
StabiliTrak
®comes on automatically whenever you start
your vehicle. However, when the transfer case is
placed in Four-Wheel-Low Lock mode, StabiliTrak
®is
automatically disabled. SeeAll-Wheel Drive on
page 2-22for more information. To help assist you with
directional control of the vehicle, you should always
leave the system on. You can turn StabiliTrak
®off if you
ever need to using the TC (traction control) on/off
button. If you press and hold the TC button for
ve seconds, the StabiliTrak
®system and the traction
control system will turn off. When this is done, the STAB
SYS OFF message will be displayed on the DIC.
Press the TC button again to turn StabiliTrak
®back on.
SeeTraction Control System (TCS) on page 4-9.
If your vehicle is in cruise control when the StabiliTrak
®
activates, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may reengage the cruise control. See “
Cruise Control on page 3-11for more information.
